Document Summary

Atelectasis at the right base; associated with elevation of the right hemidiaphragm and represents a large subpulmonic effusion. Fairly well-circumscribed shadow of homogenous density occupying the posterior segment of the right lower lobe. On lateral (b), the pleura-based density has the shape of a truncated cone and its convex toward the hilum) Thrombo-embolic fragments circulate through the rt. side of the heart & lodge in the mpa or one of its branches. Most common pathologic condition involving the lungs of hospitalized patients. Silent (80% of patients will have no symptoms) death. Thrombus can move, go into the heart, and cutoff blood circulation. In people who have deep vein thrombosis, part of a blood clot in an affected leg vein may break off and travel through the bloodstream (now an embolus). After traveling through veins and the heart, the embolus can become lodge in one of the arteries that carry blood to the lungs (pulmonary arteries).
